The Detroit Sunday Journal was a weekly tabloid newspaper published from November 19, 1995, through November 21, 1999, in Detroit, Michigan, in the United States by striking workers from The Detroit News and The Detroit Free Press. It was staunchly pro-union, and focused on labor issues as well as local news. It was one of the longest-running "temporary" newspapers ever.
There were calls for it to become a daily paper in the Detroit area, given its left-leaning tendencies and pro-union focus. The calls went unheeded, however, and it closed down as the Detroit Newspaper Strike was called off by the six unions participating in it.
